United States Patent 3,293,757 MEASURING INSTRUMENT Ove 0. Hanson, Johnson City, Tenn., assignor to Mayes Brothers Tool Manufacturing Company, Johnson City, Tenn., a corporation of Michigan Filed July 28, 1965, Ser. No. 475,411 2 Claims. (CI. 3394) This invention relates to carpenters tools and, more particularly, to a tool which has been especially designed for use by the finish carpenter.

The tool has been designed so that it can be conveniently carried by the carpenter in his pocket. It has utility for scribing, checking margins, marking margins, squaring, and, also, marking forty-five degree angles.

The tool can also be used to measure distances to a limited degree. The tool is outstanding in that it will allow a person to scribe or mark margins of door frames, window frames, and the like, and this can be done in such a way that both the upper mark and the side mark will be properly oriented as shown in the drawing.

It is, accordingly, an object of the present invention to provide an improved carpenters tool.

Another object of the invention is to provide a tool which can be used to mark in the margins of door frames, window frames, and the like in such a way that both the upper mark and the side mark will automatically read the same.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing:

FIG. 1 is a front view of the tool according to the invention shown in use;

FIG. 2 is a side view of the tool shown in FIG. 1;

FIG. 3 is a view of the tool shown in FIGS. 1 and 2 set between two parallel members;

FIG. 4 is a view of the tool arranged in a diiferent manner than in FIG. 1;

FIG. 5 is a view of the tool oriented to measure a fortyfive degree angle;

FIG. 6 is a front view of one part of the tool; and

FIG. 7 is a view of the part shown in FIG. 6 turned one hundred eighty degrees relative to the part shown in FIG. 6.

Now with more particular reference to the drawing, the tool shown in FIGS. 1 to 7 is made up of two separable parts which are the blade 13 and the handle 18. The handle 18 is an elongated, generally rectangular, relatively flat plate like member having two spaced holes therein which receive the bolts 11 which have adjusting nuts threadably received thereon. The blade 13 is a thin, rectangular, plate like member that has the parallel slots 14 and 15 which are arranged generally at forty-five degrees to the side edges of the blade 13 and each of the slots terminate at one end adjacent one of the corners of the blade 13. The blade has two holes 12 and 16 formed therein adjacent the corners opposite the slots 14 and 15. These holes 12 and 16 can be used to receive the bolts 11 to set the handle 18 to the position shown in FIG. 4 when it is desirable to use the tool as a square. The blade can have the measuring calibrations 24 thereon as shown in FIG. 7 and it can also have the angle calibrations 23 scribed thereon as shown in FIG. 6. The tool can be set up as shown in FIGS. 1, 3, 4, or 5. It can be used to check a corner such as corner 17 shown in FIG. 1. It can also be used to check a door jamb 20 as shown in FIG. 3 wherein a handle is disposed between the door jambs 20 and 21 and the blade is disposed between the door stops 22 and 19.

It will be noted that by removing the nuts 10, the blade can be set to any of the positions shown in the drawing. It will also be noted that when the tool is set up as shown in FIG. 4, it can be used as a square. When placed in the position shown in FIG. 3, the blade is in a T relation to the handle. When in the position shown in FIG. 5, the blade is at forty-five degrees to the handle.

The tool is not limited to use by carpenters but can be used by machinists and other craftsmen.

The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A carpenters tool comprising a generally rectangular shaped, plate like blade,

two spaced slots in said blade, said slots being disposed generally parallel to each other,

said slots being disposed at an angle of approximately forty-five degrees to each side of said rectangular shaped, plate like blade,

a handle,

said handle being made of an elongated member having two generally parallel sides,

two longitudinally spaced holes in said handle,

said holes each being disposed approximately midway between said parallel sides of said handle,

a first and a second bolt,

and an adjusting nut on each said bolt,

said bolts being disposed in said holes in said handle and being adapted to be disposed in said slots.

2. The carpenters tool recited in claim 1 wherein said blade has two spaced holes therein each disposed adjacent a corner of said blade opposite from the other of said slots in said blade,

said holes in said blade being disposed approximately equidistant from the opposite ends of each said slot.

No references cited.
